News in brief:

Eurostar launches a huge ‘50% off’ sale for premium seats

Eurostar has launched a new promotion, and it is well worth a look.

If two to nine people travel together (so no joy for solo travellers) you can get half-price tickets to Paris, Brussels and Lille over the summer.

What’s interesting is the deals covers Eurostar Plus and Eurostar Premier – it is very rare to see Eurostar Premier (which includes lounge access and fast track security) discounted. Both Plus and Premier include a meal.

This is how it works:

  • You can book at eurostar.com, with the call centre or in person at St Pancras
  • You must use code SUMMER25SAVINGS
  • You can only travel to Paris, Brussels or Lille
  • Between two and nine passengers must travel together
  • You can book in Eurostar Plus or Eurostar Premier
  • You must book by 11pm on 7th July
  • You must travel between 22nd July and 4th September
  • You cannot travel on 26th or 27th July or 22nd, 25th or 30th August
  • The code will expire after 10,000 bookings have been made

I assume that Eurostar Premier tickets booked under this offer retain the usual generous cancellation terms of any other Eurostar Premier ticket.

Don’t forget to sign up to Club Eurostar when booking. Our full review of Club Eurostar is here. Remember that you can top up your points after your trip with a transfer from American Express Membership Rewards at 15:1.

Beware of Hotels.com OneKeyCash expiry

It’s roughly a year since Hotels.com started to migrate Hotels.com Rewards accounts to the much-derided OneKeyCash.

What you might not know is that your OneKeyCash may actually have expired ….

OneKeyCash expires after 18 months of no activity.

However – surprise! – the OneKeyCash lump sum you received when your old Hotels.com Rewards credit was converted only has a 12 month expiry date.

A reader got in touch with Hotels.com this week after realising that his cash had expired. He said that he had not received any email notifications of upcoming expiry. This is what he was told:

OneKeyCash usually expires within 18 months when no eligible booking is made, but converted OneKeyCash only expires 12 months from the conversion date because it still follows the expiration date of your [Hotels.com Rewards] rewards nights.

Unfortunately we are unable to reinstate it because we are only following our policy.

Please accept our apologies for any inconvenience this has caused [….] we’re here for you and want to ensure you have a good travel experience.

Ensuring you have a ‘good travel experience’ seems to include, in this case, refusing to reinstate over £100 of credit ….

    Those with an Uber One account also get 10% of the Eurostar tickets refunded as Uber credits when booked through their app.

  • Gordon says:

    I only received the email from Hotels Dot com yesterday, mentioning my one key cash was expiring, use by the 4th July, bit short notice, as I’ve no time to book anything atm, but only £15 so not exactly a fortune, didn’t know I had this tbh!

  • LukeM says:

    They emailed me last year about the OneKeyCash conversion expiry date. It was ambiguous. I logged into my account and got an explicit date in February this year. It was much earlier than I expected. Anyway, I was able to use the credit.

  • teaboy says:

    There is a 50% sale on the Eurostar plus and premium tickets on SNCFconnect. I didn’t look that closely but perhaps you can get one way tickets from Paris, Brussels etc. as well as returns.

  • Rich says:

    Their T&Cs are confusing:

    “Any existing points converted to OneKeyCash will retain their original expiry dates. Your OneKeyCash (including your converted OneKeyCash) won’t expire as long as you have made an eligible booking or redeemed a redemption reward through a participating brand on your account after you become a One Key member at least once in the preceding eighteen (18) months.”

    The first sentence says converted One Key Cash retains its original expiry date; the second specifically says the exact opposite, unless I’m reading it wrong.

    • mzb says:

      I went to the T&Cs and the terms seem pretty clear. So long as you redeem or earn the expiration is pushed out. The 2nd paragraph talks specifically to converted stamps/nights from Hotels.com Rewards.

      “4.4 OneKeyCash Expiration
      Subject to the paragraph below, Base and Preferred Inventory OneKeyCash in your Account will not expire as long as you have made an Eligible Booking or redeemed a Redemption Reward through a Participating Brand on your Account at least once every eighteen (18) months. If there has been no such activity, all accumulated Base and Promotional OneKeyCash in your Account will expire and will not be reinstated. Promotional OneKeyCash may have a different expiry period, please check the offer-specific terms and conditions for details.

      OneKeyCash that has been converted from Expedia Rewards points and Hotels.com Rewards stamps and reward nights will retain original expiry dates from those programmes, unless an Eligible Booking or Redemption Reward is made through a Participating Brand on your Account once you become a One Key member in which case the above paragraph will apply.”

  • Nicholas says:

    Does having some account activity reset the clock? My conversion date was 10/07 and I have used about 1/2 of my credit… do I need to make a booking to use up the rest to avoid losing it?

    • Dubious says:

      I have not found an explicit expiry date stated in my account – making this all the more vague.

      However – my ‘Hotels.com’ account states
      ‘Last collected stamps or redeemed reward night on: Jan 16, 2024 [sic]’.

      The balance was converted to OneKey in August 2024, but if the expiry followed the original Hotels.com date they should have expired by now.

      I earned some OneKey points via two Expedia bookings in January and April this year hence I believe OneKey transactions does extend the expiry date of the converted Hotels.com balance.

      • Dubious says:

        PS..I suppose a remaining area of doubt would be the anniversary of the conversion date (August this year).

        • john says:

          Ok i looked back at e-mails and found that the

          Converted 9 Jul 2024

          +£9.54
          Hotels.com Rewards conversion

          Expired on 13th May 2025.. So might want to update the article that it expires in LESS than 12 month!

      • Rob says:

        It’s 12 months from conversion date.

        • mzb says:

          … unless you have a qualified activity after the conversion date (e.g. redeem some of the credit or earn new OneKeyCash). The expiration then pushes out by 18 months.

        • john says:

          It doesn’t seem to be.. mine expired before 12 months. I haven’t used my hotels.com account since they changed it to onekey. This is my recent activity:

          Hotels.com Rewards conversion
          Converted 9 Jul 2024

          +£9.54
          Hotels.com Rewards conversion
          Your stamp has been converted to £9.54 in OneKeyCash.

          Member reward
          Received 30 Jun 2025

          +£15.00
          Details
          This reward expires on 30 Jul 2025

          My current balance is £15 not £24.54.. so they already removed the £9.54 before 12 months.

  • SydneySwan says:

    Hotels.com turned an excellent program into a rubbish program overnight. Pure genius!

  • Swiss Jim says:

    The simplest of checks shows the Eurostar code is valid on to UK bookings and indeed is on eg Paris-Brussels…
